A man critically wounded in a shooting Saturday night in Denver continued to cling to life Sunday, as the search for the gunman got underway.

Three people were shot in a driveway at East 12th Avenue and Albion Street, which is a block east of Colorado Boulevard, at about 10:30 p.m. Saturday. The other two, a man and a woman, did not receive life-threatening injuries, said police spokesman Sonny Jackson.

A parked two-toned pickup truck is believed to be the source of the gunshots, he said.

“Two groups of folks were in a driveway when words were exchanged, and someone in the vehicle started shooting,” Jackson said.

No names have been released. Jackson said there were numerous witnesses, but police did not yet have a description of suspects.

Today, one out of every three men imprisoned in Colorado -- and four out of every five women inmates -- say they have some type of moderate to critical mental health need, according to the Colorado Department of Corrections. The number of inmates with mental health needs in Colorado's prisons has steadily risen in the past two decades.

Maybe you've got plans to camp this weekend (just watch out for the mud and, er, snow up there), go for a hike or maybe you just want to lounge by the pool and kick it. Unfortunately, Mother Nature doesn't always necessarily cooperate.
